When the Club of Rome published “Limits to Growth” in 1972, the book sold in vast numbers but its central message was also derided by many. While the book brought pollution and resource depletion into focus, the Stockholm conference that same year was belittled by many experts, especially in the West. Though more than a hundred countries took part, only two heads of government attended: The host country’s and Indira Gandhi. But she gave the wrong message for the occasion by saying that poverty was the greatest polluter.
Nevertheless, it was a path-breaking event. To mark its twentieth anniversary, the “Earth Summit” at Rio de Janeiro in 1992 drew up the Framework Convention on Climate Change. More conferences led to the Kyoto Protocol of 1997, which asked some three dozen developed economies to reduce their carbon emissions below the base level of 1990. Ratification took eight years, till 2005, with emission targets set periodically. As each target was missed, and the base year reset, there followed yet more conferences (Copenhagen-2009, Paris-2015, etc). Now principles were junked along with targets, the most important being that the principal polluters are primarily responsible for limiting and undoing the damage. Some now scoff at the very idea.
